In C#,
Make a Windows form application. It will be a four-by-four version of sudoku.
The program should start by reading in a text file of numbers and save them into a array of char. The file that you read could have a dynamic number of lines. Make sure you do not fix (hard code) the number of lines that can be read from the file.
Here are two lines to use for testing:
Zero's should not populate the board, but the other numbers should.
The next step, is for your program to populate the board based on the locations above. Create a void method called (populate) to do so. If the user clicks on the “Restart” button, the program should re-populate the board with another configuration. If the user click the exit button, the user exits the program.
Here is an example of what it should look like:
